摘要： A gasket (1) includes a body portion (10) in an annular shape having a basal surface (11) to contact a bottom surface (113) of a groove(110) and a top surface (12) to contact a second member (200) and extending over an entire circumferential direction of the gasket (1), a first protrusion pair (20) protruding from the body portion (10) respectively toward both side surfaces (111, 112) of the groove (110) and extending over the entire circumferential direction; and a second protrusion pair (30) protruding from the first protrusion pair (20) respectively toward both the side surfaces (111, 112). Respective second protrusions (31, 32) of the second protrusion pair (30) are disposed at a same position in the circumferential direction, and tip ends (31f, 32f) of the respective second protrusions (31, 32) are formed in a planar shape to be along the side surfaces of the groove (110). A first gasket width (W1) of the gasket (1) is smaller than a groove width (W0), and a second gasket width (W2) is larger than the groove width (W0).

摘要： Workability and attachment characteristics of gasket are improved. A gasket configured to be attached to a support body 51 includes: a frame-shaped attachment plate 11, a side wall part 22, a flange part 23, and a gasket body 31. The frame-shaped attachment plate 11 is fastened to the support body 51. The side wall part 22 extends along the peripheral direction of the attachment plate 11. The flange part 23 is arranged along the peripheral direction of the side wall part 22 to define insertion space 24 between the flange part 23 and the attachment plate 11. The gasket body 31 is formed of a rubber-like elastic material by extrusion to have a fixed sectional shape along its entire length, and engages the attachment plate 11 along its entire length without bonded. The gasket body includes a first seal part 32, a second seal part 34, and an insertion protrusion 36. The first seal part 32 contacts the attachment plate 11. The second seal part 34 is arranged opposite to the first seal part 32 to contact a supported body 61. The insertion protrusion 36 is inserted into the insertion space 24.
